Product Description: Quantity: 6 pieces Model: KV216 Two out of six Shell: Flame-retardant PC Internal: 304 stainless steel copper Power: 32A 600V Easy to install, no tools required. Simply plug and play! Different wires are handled separately, and different diameters can be connected securely. Built-in test point means electrical testing doesn't require removing tape. A modern alternative to traditional electrical tape and twist-on connectors, these reduce wiring time by over 50%. Ideal for detachable connections as soldering is not required. Made from premium Nylon PA66 flame-retardant insulating material. Enjoy long life, corrosion resistance, aging resistance, high pressure resistance, insulation, and flame retardancy, effectively preventing electrical leakage. Lever nuts are therefore safer than traditional metal nuts. The internal spring contact is made of copper with a special surface coating to prevent oxidation, ensuring low resistance and better conductivity. Spring clamp technology is reliable and won't fall off. Clamping force adjusts automatically to the conductor thickness, ensuring reliable contact unaffected by installation technique.
